Reverse osmosis and nanofiltration pilot

This water treatment process is a membrane separation technique whose motive force is a pressure gradient. Its interest lies in the fact that some molecules (10-6 to 10-7m) and some ions are stopped, while the molecules of the solvent pass. The energies involved are greater than those of processes with similar objectives.

This technique makes it possible to obtain a pure solvent and to concentrate in ion, hence its use in applied fields such as the desalting of seawater, the softening or the treatment of waters containing metals.
